Multiple versions of Acrobat on same system?

[Diane Gaskill]

I've read several discussions on this list about multiple versions of FM
runing on the same system (it works).  Can multiple versions of Acrobat also
run on the same system?  I recently installed Acrobat 7 on my system (XP2)
but did not uninstall Acrobat 5.  Acrobat 5 now displays an error message
and closes.
